Table 3.37 PBX 9401 (RDX/PS) ON DURAL<br />

DETONATION PROPERTIES<br />

RDX/PS/‘TOF: 94.2/3.6/2.2. 1.713 f 0.002 g/cm’. A 203-mm-thick conical<br />

frustum of 229-mm small diameter and 324-mm large diameter with its small end<br />

toward the plate. P-080 booster. D = 8.426 km/s at p. = 1.711 g/cm’.<br />
